DEVICE FOR FILLING GREASE-CUPS.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 2, 1907. Serial No- 350,391.

T 0'. whom, it may concern:

Be it known that I, HARRY S. ERD, a citizen of the United States ofAmerica, residing at Saginaw, in the county of Saginaw and State ofMichigan, have invented certain new and useful Improvements in Devicesfor Filling Grease-Cups, of which the following is a specification.

This invention relates to new and useful improvementsinfilling cans andit is intended more especially to be employed with plastic lubricants.

It is an object of this invention to provide a novel device of thischaracter whereby the lubricant is discharged through the medium of theplunger.

It is also an object of this invention to provide in a device of thischaracter, means acting in conjunction with the plunger for controllingthe movement of the lubricant to be discharged.

It is furthermore, an object of the invention to provide in combinationwith a device of the character described novel means for excluding dusttherefrom, when the same is not in use.

Finally an object of this invention is to produce a device of thecharacter noted, which is simple in construction, efiicient in practiceand comparatively inexpensive to manufacture.

WVith the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In'describing the invention in detail reference will be had to theaccompanying drawing forming part of this specification wherein likecharacters denote corresponding parts, in which figure given is acentral vertical section.

In the drawing, 2 denotes the body of the can which may be in the formof a cylinder having its upper end closed by the top 3, while the bottom4, thereof is inclined or funnel like in construction and provided witha central aperture 5.

Diametrically opposed and secured to the upper portion of the body 2,are the standards 6, which are engaged by the cross strip 7, saidengagement being afforded byperforations 8, in the cross strip throughwhich the standards pass. The ends of the cross strip are provided withthe threaded recesses 9, which communicate with the perforations 8.

Engaging the threaded recesses 9, are the screws 10, which are intendedto contact with the standards and hold the cross strip 7, in variousadjustments on said standards.

Within the can is a piston or plunger 11, corresponding in contour tothe interior shape of the can. This plunger is provided with a rod 12,extending upwardly and passing through an aperture 13, in the top 3, ofthe can and through an opening 14, in the cross strip 7. To the upper orfree end of the rod is threaded or otherwise attached a hand grasp 15.In practice the plastic lubricant is placed within the can and theplunger 11, positioned thereabove. The cross strip 7, is positioned at apredetermined point upon the standards 6. iVhen desired to force thelubricant within the cup, the rod 12, is pressed until the hand grasp15, comes in contact with the cross strip 7. By having the cross stripobstructing the movement of the rod prevents the cup from being filledto overflowing. This has been found a great advantage as ordinarily theapplying of plastic lubricants to the cups is a difficult operation andthe disadvantages of having the cup overfilled are manifold. It is to bestated that as the can 2, is being emptied the cross strip is adjusteddownwardly on the standards. In order that dust or other foreignsubstances may not enter the body 2, through the opening 5, in thebottom 4, thereof when the can is not in use, a receptacle 16, isemployed into which the filling can snugly fits.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is,-

In combination, a body having an opening in one of its ends, standardsprojecting from the opposite end of the body, a cross strip havingperforations through which the standards extend and having a centralopening,

said cross strip also having threaded recesses in its ends communicatingwith the perforations, screws engaging the threaded recesses to bindagainst the standards, a plunger within the body and a rod for theplunger passing through the opening of the cross strip.

In testimony whereof, I afiix my signature in the presence of twowitnesses.

HARRY S. ERD.
